Making strawberry brownies is quite straightforward if you follow these steps carefully:

1. Preheat Oven: Begin by preheating your oven to 350°F (175°C). Grease and line a 9×13-inch baking pan with parchment paper.
2. Mix Wet Ingredients: In a large bowl, combine the melted butter and granulated sugar. Stir until well mixed. Add the eggs one at a time, followed by the vanilla extract. Mix until smooth.
3. Combine Dry Ingredients: In a separate bowl, sift together the flour, cocoa powder, baking powder, and salt.
4. Combine Mixtures: Gradually add the dry ingredients to the wet mixture. Stir until just combined. Be careful not to overmix.
5. Add Strawberries: Gently fold in the sliced strawberries and chocolate chips if you’re using them.
6. Pour into Pan: Spread the brownie batter evenly into the prepared baking pan.
7. Bake: Place the pan in the oven and bake for 30-35 minutes. The brownies are done when a toothpick inserted in the center comes out with a few moist crumbs.
8. Cool: Let the brownies cool in the pan for about 15 minutes before transferring them to a wire rack to cool completely.
9. Slice and Serve: Once cooled, slice into squares and prepare to enjoy!
